is torvald a protector/savior or a controlling, self-centered tyrant?

Although he loves Nora,Torvald doesn't understand her or women in general. In that sense he is self-centred, he just doesn't know any better. I wouldn't call him a tyrant. He doesn't abuse Nora. Torvald is controlling but again, it's like he doesn't know any different. Like many men at the time he operated in a patriarchal world.
